 the ballistic block has an end face having a stepped configuration on an outer periphery of the bullet-proof glass pane, 
 the stepped configuration is stepped down from an outer side to an inner side of the bullet-proof glass pane, and includes at least two planar end surfaces extending in parallel and offset with respect to each other, and 
 the at least two bullet-resistant strips correspond to the at least two planar end surfaces of the ballistic block and cover the at least two planar end surfaces of the ballistic block in a flush manner. 
 
     
     
       2. The bullet-proof glass pane according to  claim 1 , wherein each of the strips is of metal including ballistic steel. 
     
     
       3. The bullet-proof glass pane according to  claim 1 , further comprising at least one outer pane of glass, ceramic or plastic bonded to the ballistic block on a side on which the ballistic block is configured to receive impact,

       4. The bullet-proof glass pane according to  claim 1 , further comprising an outer pane of glass, ceramic or plastic bonded to the ballistic block on a side on which the ballistic block is configured to receive impact,
 wherein the outer pane protrudes from the ballistic block and the at least two strips at the outer periphery of the bullet-proof glass pane to form a protrusion of the bullet-proof glass pane for mounting the bullet-proof glass pane on or in a frame or rabbet of a body of the motor vehicle. 
 
     
     
       5. The bullet-proof glass pane according to  claim 4 , wherein the protrusion of the bullet-proof glass pane has a stepped configuration. 
     
     
       6. The bullet-proof glass pane according to  claim 1 , wherein the strips have same thicknesses
 in a first direction normal to the bullet-proof glass pane or 
 in a second direction parallel to a plane of the bullet-proof glass pane. 
 
     
     
       7. The bullet-proof glass pane according to  claim 1 , wherein the strips are bonded to the ballistic block as edge reinforcement. 
     
     
       8. The bullet-proof glass pane according to  claim 1 , further comprising an edge-side protrusion that is flush with one of the strips. 
     
     
       9. A bullet-resistant apparatus for a motor vehicle, the apparatus comprising:
 a bullet-proof glass pane including
 a ballistic block having
 a plurality of panes of glass, ceramic or plastic material, and 
 interlayers of plastic material interposed between the plurality of panes, wherein said plurality of panes are bonded to each other, by the interlayers, over corresponding surfaces of the panes in a layered composite; and 
 at least one bullet-resistant strip having a substantially rectangular cross-section and covering a peripheral edge of the ballistic block; and 
 
 
 a bullet-resistant armoring device configured to be arranged inside the motor vehicle adjacent to the bullet-proof glass pane and overlapping an area of an outer periphery of the bullet-proof glass pan; 
 wherein the armoring device has a stepped configuration engaging and overlapping a part of the ballistic block. 
 
     
     
       10. The apparatus according to  claim 9 , wherein the armoring device supports the bullet-proof glass pane. 
     
     
       11. The apparatus according to  claim 9 , wherein
 the ballistic block of the bullet-proof glass pane has an end face having a stepped configuration, 
 the stepped configuration of the armoring device corresponds to the stepped configuration of the ballistic block in such a manner that the stepped configuration of the armoring device engages and overlaps the stepped configuration of the ballistic block. 
 
     
     
       12. The apparatus according  claim 9 , wherein the bullet-proof glass pane is mounted in or on a frame or rabbet of a body of the motor vehicle and the frame or rabbet supports the bullet-proof glass pane. 
     
     
       13. The apparatus according to  claim 12 , wherein the bullet-proof glass pane at the outer periphery thereof has a protrusion configured to be attached or bonded to a stepped profile of the body of the motor vehicle. 
     
     
       14. The apparatus according to  claim 13 , wherein
 the protrusion of the bullet-proof glass pane has a stepped configuration at an end face of the bullet-proof glass pane, and 
 the stepped configuration of the protrusion of the bullet-proof glass pane is configured to correspond to the stepped profile of the body of the motor vehicle and engage the stepped profile of the body of the motor vehicle.
